So, CyberDefender (aka MyCleanPC) wanted to 'explain' to me just how a virus can cause permanent damage to a computer. Lets break down their response.
Its a fantastic way of making highly questionable claims that will scare the less tech savvy people into thinking that they just must get your service.
This should be good.
Except that all semi-modern processors (esp. since the Pentium 4, but I do believe theres protection going all the way back to the Pentium) have whats called thermal protection - this means that once the processor hits a certain temp threshold, it throttles back the processor to prevent permanent damage. Slowing down the processor will reduce the heat levels. Once the heat levels are down below the limits, the processor goes back to full speed.
If the temp rises to critical levels, the processor/motherboard will shut off the system. Once again, this is long before permanent damage will set in.
Once again, built in thermal protection on the motherboard will prevent this. There's certain functions of every motherboard that are part of base functionality that can't be disabled by a virus or operating system.
You must not understand how a hard drive works - the head of the drive never touches the platters. It doesn't work like a old style audio record with a stylus needle. Wear happens regardless of what the drive is doing - any time Windows needs to read or write a file, or when the Windows virtual memory manager begins to thrash the disk wildly.
Now, if this was a flash memory device, writing to one sector repeatedly would damage it, however, once again, in most flash drives there's hardware wear leveling which means that the sector you are writing to isn't always the same sector it was a moment ago.
Informative indeed, told me exactly what I already knew - that your knowledge of how a computer works isn't exactly accurate.
